Submagic

Edit shorts 10x faster with AI

Overview

Submagic has become one of the most recognized names in AI captioning specifically because it goes beyond captions: B-roll insertion, zoom effects, bad-take removal, and eye contact correction all happen automatically, which is why it's popular with creators who want a finished, editor-quality short without touching a timeline. The 48-language support and premium b-roll library (real movie clips on higher tiers) also set it apart from more basic caption tools.

The tradeoff is cost and video caps: even the entry Starter tier is capped at a set number of videos and video length per month, and the features most people want (premium b-roll, longer max video length, API access) are locked behind the Pro and Business+API tiers at $39-$69/month. For occasional posters the free or Starter tier is fine, but agencies and high-volume creators will likely land on Pro or Business, making it pricier over time than simpler caption-only tools.

Key Features

  • AI Caption Generator: Auto-generates animated captions in 48 languages with high accuracy, styled for social platforms.

  • B-Roll & Movie Clips: Automatically inserts relevant B-roll and, on higher tiers, premium movie clip footage to keep viewers engaged.

  • Eye Contact Correction: Adjusts on-camera eye gaze for a more engaging, direct-to-camera look.

  • AI Hook Titles & Clean Audio: Suggests attention-grabbing hooks and cleans up background noise and bad takes automatically.

  • Magic Clips: An add-on that extracts viral-worthy short clips from long-form source videos.

  • API Integration: Business tier includes API access to plug captioning into an existing content pipeline.

Cons
